The worse the primary-caregiver's job prospects are, the cheaper the opportunity costs are to have kids. My wife quickly realized she didn't want to be an English teacher, and couldn't do a whole lot of other things with that degree, so her staying home to raise our 4 kids was very affordable for us. If she had been a software developer, the opportunity costs would have been higher.
